And all this was from a puppy. Just think what an average sized bear could do if he wanted inside one of these RVs.

Or a crook with a size 12 boot and a screwdriver.... Many people have the "false sense of Fort Knox" when inside an RV. Most of our trailers are nothing more than a "rigid wall tent" when it comes to getting inside or getting outside, either through a door, a window or even through the wall. Cardboard backed fiberglass sheeting sandwiched to 1.5" of white Styrofoam board and a 1/8" sheet of cheap plywood covered in "designer vinyl wallpaper" doesn't stop much of anything or anyone who is determined.

My line for someone who "lost" their keys...I have a universal set of keys, it's called a size 15 EEE shoe. LOL.
Modern bonded side campers remind me of walk in coolers and freezers, except they are built better.

The "They are built better" was referencing the walk ins. They are typically a sandwich of 2 aluminum sheets which may or may not be covered in FRP with 2" of foam in between. The doors are hinged on heavy cam hinges that makes the doors mechanically self closing with a robust door latch/handle. All Fitting are stainless steel. Walls and ceilings are mechanically fastened with cam locks and all joints are sealed with an o ring type material..

don't think it's a puppy. looks like full size blue heeler. never met one I liked. but, I don't raise cattle.

Yep, a blue heeler for sure. Those and Border Collies should not be kept as house pets. They are working dogs that are highly intelligent and border on OCD. They need to burn off LOTS of energy and when cooped up in a house with nothing to do, they go mental.
My SIL had a Border collie as a pet and it loved to fetch a tennis ball. The thing is, that dog would chase the ball until it dropped dead from a heart attack if you kept throwing the ball.

We have a Boston Terrier/Blue Heeler mix. We adopted her when she was about 8 months old. She's about 2.5 now, she's been an awesome dog for us. She travels well, doesn't destroy anything and has been content with daily games of fetch at the dog park.

We lived in a sticks and bricks house with a fenced back yard when we got her, been in the travel trailer for a little over a year now.
